I’d like to encourage you to update to 4.7.5 as soon as possible. Unless you have disabled automatic updates, your site may have already been upgraded to WordPress 4.7.5. This security release was a ‘minor’ release and WordPress by default automatically updates core minor releases.

I have used the term ‘abrupt’ to describe this release because it went out without much pre-announcement. I’m concerned that this release may have fixed more than the vulnerabilities that have been detailed on the WordPress blog. That would not be without precedent.
